Talks are due to take place to discuss the future of a major contract held by a Dumfries-based building firm which has gone into administration.
It was confirmed on Friday that 205 of the 226 staff at R&D Construction were being made redundant.
It is understood administrators were called in as debts became unmanageable, despite a £70m deal to build 600 homes for social landlord DGHP.
Unions hope a takeover of the contract could see some workers re-employed.
Paul Bennett, of construction union UCATT, said that ideally anyone taking up the project would use the expertise of the staff who had already been involved.
"The client, DGHP, still has to get this work done that predominantly R&D was doing," he said.
"So somebody else has got to carry on with that work and it would make sense to use the labour who have the experience and have the knowledge of those sites."
DGHP has described the situation as "extremely complex" and requiring "a lot of consideration".
It said it would continue talks with administrators in order to make "an informed decision about the most appropriate way forward".
